Presents a study which assessed preschool children's understanding of "front,""back," and "side" through a variety of tasks. A developmental sequence is defined. (ED)

"More" and "less" were analyzed into two meaning dimensions, "occurence" and "quantity", which were hypothesized to be developmentally related to acts of addition and subtraction. (SBT)

Suggests a set of activities that foster physical and intellectual growth through thought-provoking situations which require no special equipment and can take place indoors or out. (MP)

Preschool children were trained to acquire transitivity, conservation, and class inclusion of length via feedback to their judgments. Feedback was found to facilitate the learning of all three concepts. (ST)

In the follow-up study, most of the initial gains in IQ resulting from program participation were retained. (Authors/MB)

This study compared the effects of a formal, an open-framework, and a control preschool program on children's intellectual development. The formal program, based on Ausubel's and Piaget's theories, had a daily schedule of short prescriptive teaching sessions followed by related learning activities. The informal program, based on Piaget's theory,…

This comprehensive bibliography on problem solving and concept formation includes books, papers, journal articles, reviews of literature, projects, unpublished manuscripts, reports, research bulletins, dissertations, and related bibliographies dating from 1924-1967. Special annotations are made of materials on problem solving with young children.…

Assesses comprehension of the mental verbs "remember" and "forget" among three-, four-, five-, and seven-year-old children by having the child judge whether or not toy characters in different situations remembered or forgot. (Author/RH)

Preschool children were required to act out a series of two-event sequences conjoined by either "before" or "after." Performance was markedly superior for meaningfully ordered sequences than for arbitrarily ordered sequences. It is suggested that the meanings of "before" and "after" must be acquired in situations which provide contextual support.…

The recent experimental literature on the acquisition of English antonyms is reviewed, with special reference to the position of Eve Clark and the particular ontogenetic assumptions her position entails. The assumptions examined are: (1) in a hierarchically organized lexical domain, the order of acquisition appears to be from the top of the…

The hypothesis that the acquisition order of relational words directly reflects the complexity of these words in formal linguistic analysis was tested for the singular, non-neuter person pronouns of English. Data on the development of comprehension of these pronouns gathered in two conversational situations, child as person addressed and child as…

Program planning for economically deprived children might be improved if behavioral information pertinent to specific subcultural groups were systematically obtained. This prospectus focuses on developing a three-part behavioral model which, when integrated, would identify and profile the nature of disadvantagement in terms idiosyncratic and…

The purpose of this research was to develop methods to study the effects of context on children's comprehension and production of temporal terms such as "before,""after,""next,""then," and "but first." A longitudinal study, using naturalistic and traditional laboratory methods, and three…
